# #9645 [main] bug 642743 - Change behavior of OnValidate trigger of "EU 3-Party Intermed. Role CZL" field

> When the EU 3-Party Intermediary field is deactivated in sales or purchase document headers, the EU 3-Party Trade field is now also deactivated instead of remaining active.

[Pull request](https://github.com/microsoft/BCApps/pull/9645) · merged into `main` (BC30) on 2026-07-23 by DavidHolusa · 2 files (+2 -4), 2 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Fixed inconsistent validation behavior where setting EU 3-Party Intermediary to false did not clear the EU 3-Party Trade field
- Ensures both fields stay synchronized during activation and deactivation
- Applied to both Sales and Purchase document headers in the Czech localization
- Behaviour changes for users or extensions.
